Open source tuning solution

[Diggs24]

I need to find this SIMOS guy. Sounds like a real baller.

Diggs tuned with SIMOS tool? Whatever man.

I just want open source tuning for mk8 and a 1000hp Diggs tune.

SIMOS has what engines crave

Guys, thanks for all your hard work on this. Took the plunge last week to unlock, tune, and flash my GTI. It's incredible to have this level of control and support over the ECU from the community. So so glad I decided to take the time to learn instead of going with an OTS tune, even more so that I managed to not blow it up ha. I look forward to improving my tune and helping out with the knowledge base with this effort.

Best, Alex

Got any of that SIMOS crack for mk8?

The EQT is undriveable on track. Throttle isn't linear and all the torque hits like a hammer at 4000 rpms, and just lights the tires up.

Anyone running tunerpro in a VM on a M-series Macbook? or should I buy a cheap windows 7 laptop..

I used Crossover windows emulator in my M2. It worked… fine. Not perfect and had weird issues when resizing windows, but got the job done. A true Windows experience like Parallels would probably work better.

eBay has lots of barely-OOW Dell Latitudes for cheap, most of which can easily be coaxed into running Windows 11. OR, you can use ECUleg and tune from an Android device, which would enable you to use the same device for flashing that you're already using for tuning. With that said, I've gotta shill MegaLogViewer for viewing lots of data at once, Datazap is great for sharing but MLV makes it easier to view large swaths of things at the same time.

ECUleg is a great option because you need and Android device to flash and log via Simos Tools anyways. Get an Android tablet and let that be your dedicated tuning thingy.

also beneficial because it's much easier to migrate Android devices IMO than it is to get new Windows devices, particularly tablets that don't suck. I've seen a large number of USB-C ports wear out on laptops where they're used for docking stations/charging, and it's a bummer because generally speaking that means replacing the motherboard. On an Android phone you're able to do just about everything wirelessly, so it's a much more stout device, and if using OneDrive/Google Drive/Dropbox/etc to back up files and a Google account to back up your local phone settings/profile stuff, it's not hard to migrate hardware without too much issue.

Computer-side, I've been using Macrium Reflect to do drive image backups to mitigate any major issues BUT there are some caveats that make it less than perfect in some instances, and in general I really wish a cheap Windows tablet with keyboard cover a la Surface Go or similar were more readily available.

Don't just ask for invites. A better idea would be to tell me/us:

1. What your current setup is (hardware, tune, etc)
2. What your prior tuning experience is
3. What your technical background is
4. What your goals are


This really is a red pill or blue pill situation. You take the red pill, you'll lose your current tune if you have one and you'll retune your car from scratch. You'll need to learn a lot of new stuff. You may never live in peace again because you'll always have the ability to tweak. You'll see the world of tuning differently and you won't sleep as easy at night. The red pill isn't for everyone.

I joined this forum for this thread. Firstly, thank you to everyone who has contributed to making this what it is! I decided I would read all (at the time of this writing) 36 pages before posting or asking anything. I found this thread after I decided that I was fed up with my current tune and setup. I started hunting for the ability to self-tune ( I have no tuning experience). I found a YouTube video of Joe doing a flash with the VW_Flash. That led me on a larger hunt, and this thread kept coming up. I've already applied and was accepted today to the FB group (haven't posted there yet). I plan to learn from there before asking about the Discord group.
I am excited to dive in and learn. I hope to contribute to the cause.

I bought my new-to-me 2016 GTI (nov. 2024) after someone put a second engine in it. The first one developed "crank walk". I bought it with all the mods listed below. Since day two of me owning it, it has had oil pressure issues that I have been chasing to resolve, and now there is a knock coming from the engine and it won't stay running. Pretty sure this second motor is toast as well. So, in preparation for a third motor after my move from Hawaii to Austin, I plan on not running the REVO tune as I honestly never had heard of them before this car as they aren't one of the main one's I have seen. I don't trust it and contribute it the issues that the car has been having. (2 motors down).

1. Current setup:

• CXCA Engine with 75k miles (will be replaced lots of metal in oil and filter)
• IHI IS38 Turbo (May replace, not sure if I can trust it with metal in oil)
  • Believe wastegate spring was changed based on receipts, but not sure to what.
• CTS Bolt-on everything
  • Intercooler
  • Charge pipes
  • Intake
  • Turbo back exhaust
• Stage 3 ECS Clutch
• REVO Stage 3 Tune
• Other non-performance parts have been updated / replaced as well

2. Prior Tuning Experience
- No tuning experience, but willing to learn


3. Technical Background:
- Software: I know it isn't a direct translation, but like many others on here. I am in the IT field I know python, bash, linux, sql & nosql databases and many other tools and systems.
- Cars: I have always owned VWs and worked on them myself. The most recent prior to the mk7 was a mk1 cabby with a VR6 swap. During COVID I did the cams and physically chipped the car outside of just the swap.

4. Goal:
- To be honest, I'm not looking for the 1000hp break your car build which I feel like the REVO tune was trying to do.
- I like the mods that were done and I just want to start with a safe profile that I can use to daily the car with the current mod lists and it feel quick/fast without worrying that I'm going to blow up the block. and slowly tweak over time or have a more "risky" profile for those extra spirited days.

I am curious if I can do different tunes pre-selected based on whether it is in sport mode or normal mode.

You can do different tunes with mapswitching.

I'm still learning is that off of simostools or that's a patch to the ECU

That is thanks to Switchleg's work building the patch 'SwitchPatch', which enables a much better traction control system, launch control, map switching, and some other stuff I don't fully understand. But for what you're after, yes on-the-fly map switching is easily available, meaning you can drive down the road on a more economical tune and then see something fun, hop over to your aggressive map, and then go dominate the skreetz. All without ever having to stop driving.

SimosTools allows you to flash from an Android device, SwitchPatch is a patch for the stock BIN file applied using BINToolz.
